, I 11 Claims. 1 This invention relates to new and useful improvements in knittingv machines of the so-called links and links type; and more particularly, it pertains to a new and improvedcarriage rail support for such machines.

Machines of the so-called links andlinks' type consist of a frame in which is mounted a I pair of needle beds over which travels a carriage.

- ends, there being no intermediate attachment for v the rail. Such a construction has been found to have disadvantages in that, in the case of relatively long machines, this rear carriage rail. has

a tendency to get out of true alinement, thereby throwing the carriage out of proper relation to n other parts of the machine with which, inv order to produce the best results, it is necessary to I maintain alinement.

I It is the object of the present invention to improve the construction of the rear carriage rail of links and links knitting machines and to provide means whereby adjustment of the rear carriage rail is provided.

A feature of the invention resides in a new and novel construction and arrangement of parts whereby the rear carriage rail of a links and links knitting machine may be supported at a 1 number of points throughout its length.

.A further feature of the invention resides in the provision of a new and novel form of supporting means which will permit of adjustment of the rear needle rail in such a manner that any sagging, which mightbe present may be removed. f A further feature of the invention resides in the provision of new and novel means whereby the rear carriage rail of a knitting machinemay be adjusted ina lateral direction. 7 It is stilla further feature of the invention so to construct the lateral adjusting means that the carriage. rail will be held against accidental displacement in the position to which it may be adjusted, by said means.

A still further feature of the invention resides in the provision of means whereby the supporting means may be retained in its adjusted position.

Various other features of the invention will I become apparent as the nature thereof is better understood, and reference will, therefore, be had in Figure l.

to the following specification and claims and the accompanying drawings, in which:

Figure 1 is a view in elevation partly broken awayshowing a rear view of a portion of a links and links knitting machine,

Figure 2 is a transverse sectional view taken substantially on the line 2--2 of Figure 1,

Figure 3 is a similar view taken substantially ontheline 33 of Figure 1,

Figure 4 is a distended perspective view illustrating the new support,

Figure 5 is a fragmentary view in rear elevation partly broken away of a portion of a knitting machine frame illustrating a modified form of the invention,

Figure 6 is a transverse sectional view on an enlarged scale taken substantially on the line 6-6 of Figure 5,

Figure 7 is a transverse vertical sectional view taken substantially on the line 'l'l of Figure 5, the view being enlarged,

Figure 8 is a horizontal sectional view on an enlarged scale and taken substantially on the line 8-8 of Figure 5, and;

Figure 9 is a detail distended perspective view.

Referring to the drawings, and particularly to Figures 1 and 4, inclusive, the reference numeral 5 designates the frame of a links and links knitting machine, which frame may be of any approved desired construction. The reference numeral 6 designates the rear needle bed which is provided with grooves 1 in which are mounted for free sliding movement needle jacks 8 and needle jack'pushers 9.

It is because-of the presence of the rear ends of the needle jack pushers 9 beneath the rear carriage rail which is designated I0, that means for supporting the rear carriage rail I0 at points intermediate of its ends has heretofore been a problem, and it is the overcoming of this problem that the present invention aims to effect.

In the general construction of machines of this type, a comb rail l2 having a plurality of spaced teeth receives the rear end of the jack pushers 9 to support the same when. they are in their fullyextended position, as illustrated in Figure 2. This comb rail is generally supported by a bracket I3 secured to the frame in any desired manner, such as by bolts it, as illustrated The devices of the present invention are adapted to be secured to this comb rail 2 and are adapted to engage beneath the carriagerail IO. These devices consist of a block 15 which, as more clearly illustrated in Figure 4, consists of a main body portion having a lug I6, a'plurality of elongated slots l1 and a plurality of spaced teeth, the latter being formed upon the upper edge of the block. The teeth i8 are of substantially the same dimensions as the teeth of the comb rail 12 and the spaces between the teeth I8 of the block l will also be of the same dimensions as the space between the teeth of the comb rail. The blocks l5 are adapted to be secured to the comb rail I2 by means of bolts or the like I9 which pass through the slots I1 and engage threaded openings in the comb rail l2. When the blocks I5 are placed upon the comb rail it will be understood that the teeth 18 of the blocks will be lined up with the teeth of the comb rail in order that the rear ends of the several jack pushers 9 may pass as freely through the blocks l5 as they do through the comb rail l2.

Means is provided to adjust the blocks l5 relative to the carriage rail I0, and this means consists of a threaded bolt 25 threaded in an opening 26 in a bracket arm 21, which in turn is secured to the frame 5 by means of bolts 28, see

Figure 3. The upper end of the bolt 25 engages the under face of the lug I6 of the block l5, as illustrated in Figure 3.

From the foregoing construction it will be apparent that if the bolts H] are loosened, the block i5 may be moved vertically either upwardly or downwardly merely by an adjustment of the bolt 25. After the bolt 25 has been properly adjusted, a jam nut 35 may be adjusted to hold the bolt 25 in its adjusted position. After the has been adjusted to the desired position, the bolts it are tightened, clamping the block E5 to the comb rail I2 in order that the block may be held in its adjusted position.

While in the foregoing specification, the device has been described as a single device, it is to be understood that any number of these devices may be employed and that in the case of a number of such devices being employed, they will be independently operable as to adjustment, thus providing means whereby the rear carriage rail of a links and links knitting machine may be supported at points intermediate of its ends, and further, that the supports are adjustable in order that the rear carriage rail may be adjusted to remove therefrom any sagging which may be present therein and to support the carriage rail in a manner which will prevent sagging thereof.

In the modified form of the invention illustrated in Figures 5 to 9, inclusive, the frame 5, bracket arm 21, threaded bolt 25, jam nut 30, and comb rail i2 are of substantially the same construction as in the preferred form of the invention heretofore described.

The blocks, in this form of the invention, however, are different from the blocks i5 heretofore described in that said blocks, which are designated 56, are provided with three elongated openings 6!, 62, and 63. The elongated slot 62 is disposed centrally of the block 50, the slots 56 and 63 being located closely adjacent the ends thereof. In this form of the invention the blocks are also provided with two threaded openings 6'5, and these threaded openings 64 are locatbetween the central elongated slot of the end slots, as shown in Figure 9. In this form of the invention, the blocks 60 are secured to the comb rail l Zby bolts 66 and 61 which pass through the eiongated slots SI and 63 respectively in the block E50, and have threaded engagement with ported from the angle bracket 68 by means of a bolt (it which has threaded engagement with the angle bracket as at in Figure 8.

The construction just described provides for vertical adjustment of the blocks 60 in order that any sag in the carriage rail 88 may be eliminated merely by elevating one or more of the blocks 60 until the carriage rail is in its proper position after which the remaining blocks are moved into supporting engagement with the under surface thereof.

In this form of the invention means is provided for lateral adjustment of the carriage rail, and this means consists of two bolts I2 which are threaded into openings B l in the blocks 69 and have engagement withthe comb rail i2, as illustrated in Figure 8. It will be noted that in this form of the invention the toothed edge of each block 60 is received in a recess E6 in the ca'rriage'rail 80. This construction is provided so that when the blocks 69 are moved laterally,

the rail 8% will be. moved in the same direction by reason of interengagement with the teeth of the blocks 68 in the recesses It in the rail.

To effect an adjustment in a lateral direction, for instance to the right in Figures 6 and '7, the bolts 66, 6'! and 69 will be backed out while the bolts 12 will be tightened into engagement with the comb rail 12, thus moving the block to'the right in said Figures 6 and 7. To effect an adjustmentto the left in said Figures 6 and 7, the bolts l2 will be backed out while the bolts 68 and 6'! will be tightened'to move the block 60 to the left in Figures 6 and 7.

From the foregoing it will be seen that the modified form of the invention provides, in addition to means for adjusting the carriage rail in a vertical direction, means by which the carriage rail may also be adjusted'laterally, thus providing 7 means for full adjustment of the carriage rail.

While the invention has been herein disclosed in its preferred forms, it is to be understood that it is not limited to the specific construction herein illustrated and that it may be practiced in other forms without departing from the spirit thereof.
